PLOW.

Application filed November 24, 1915.

To all ir/iom it may concern lie it known that I, i\l.\S.\KICI-II YAMA- oL'eni, a subject of the Emperor of Japan, residing at. Seattle, in the county of King and State of llashington, have invented certain new and useful Improvements in llows; and I do hereby declare the following to he a lull clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plows, and to particularly the class of plows for use on rough or hilly ground where it is desirahle down hill. One object of this in vention is to provide a plow with both sides made similar and sloping side, and to provide means for adjusting and holding the plow at the angle desired in ordinary side hill use, and particularly for nolding the plow portion in position to throw the fur-row continuously in one direction while the plow is being moved to and fro.

In the drawings Figure 1 re )resents a side view of the plow complete: wig. 2 represents a top view of the shovel portion of the plow; Fig. 3 represents a back view of the plow; Fig. 4 represents a detail plan of latch for reversing lever; Fig. 5 is a rear elevation of a slightly modified form of the guide for the lever; and Fig. 6 is a perspective detail of the connection at the rear end of the plow-shank, with the parts thereof slightly separated.

Like numerals refer to like parts in different views.

I, rc 'n'esents orrefers to the. single stand ard carrying a handle for guiding the plow, and 2 is the i'n'dinary beam. 3 the plow or shovel. 4 the hand hold at top of 1, 5 is a loop for holding in place the reversing lever (i, T is the handle for operating the latch pin '1'", and 7" is coil spring for holding the latch pin in a normally extended posi tion outward from the seat 7" cut into the front side of the lever G.

8 shows a point which is held in position on the shovel 3 by a screw or bolt 9, and 10 shows the heel inclined upward at the rear portion of the plow shovel,

12 is a cross bar securely fixed to the standard 1 at right angles thereto and car rying tho loop 5 which is bent hiu-kward.

and downward to permit the reverse lever Specification of Letters Patent.

being ()l'lEl'lItLll between its portion parallel w th cross bar 12, the downward bend perpnttinlg the tree swing of the latch handle I with the reversing lever.

11, ll shows the holes in cross bar 12 into which the latch pin T his to hold the lever in its res n-ctive positions, and so hold also the plow shovel tipped to either side. It will be readily seen that by forming the cross bar on a curve with its center at highest point as seen at 12 in Fig.5 and pro viding it with a number of holes 11' the latch pin would travel in the sainearc as the curve of the bar and so enable the op erator to hold the shovel in any desired position between the two extremes shown here on the drawings; but for the purpose simplest form of the invention deem it sullicient to show the cross ba'r 12 in Fig 3 as straight with only two holes.

13 is a shank projecting to the rear from the transverse center ol the shovel. This and slidably and rotatahly mounted through the lower end of stand ard 1. It provided with a tenon 13 at its rear end, which tenon is-of angular and preferably square cross section as best seen in Fig. (3, and a correspondingly shaped hole (5 through the lower end of lever (3 permits the lever to than fit over the tenon so that as the lever is moved sidewise the shank 13 is turned 0r oscillated on its axis and the shovel adjusted as desired. A suitable wide headed screw J7 holds the lever (l on the said square tenon. A suitable heavy coil spring 14 is fitted around the shank 13 between the standard 1 and the shovel 3 which holds theshovel normally pressed forward from the standard, but when the point, 18 strikes a root or stone certain elasticity is provided by the spring ll which tends to reduce the shock or ja r that is co|nmonly experienced by the operator or mechanism on such occasions. The point 8 is preferably beveled at 18 to slope downward at a sharp angle and so holds the plow in the ground while the depth of the furrow is further regalated by adjusting the draft in the holes of the clevis at the front of the beam 2. V

In operation'the horse or other power is attached and the plow is oscillated by the lever and set at the desired angle to right or left to agree with the side slope of the surfar-e to he plowed, to turn the furrow down the slope, as the operator guides the. lion rhino with the handle 4. When he has plowed a furrow across the side hill and r a hed its end, he turns the horse and plow around preparatory to returning aeross the side hill in the opposite direction for plowing: the next furrow; but now. in order to again turn the furrow down the. slope. he must reverse the position of the shovel as will he elear. This is au-eianplished h disengaging: the lateh pin T from one. extreme hole ll as seen in Fig. 3, and throwin; the lever over to the other end of the loop I: and engaging: the pin with the opposite extreme hole. It holes exist between the two extremes, as seen at ll in Fig. 3. they are ohviousl servireahle for permitting: the all justnlenl; ol' the lever at points hetween its extreme positions. as is desirahle when he does not wish to set the shovel at. its extreme angle. to either side. lint whether said shovel is set t its extreme or in an other iosition. when it strikes an ohstruetion it will he elear that the spring ll serves as a shoek ahsorher to prevent fl'ttt'tlll'l' of parts until either the olIstrIu-tion is overeoine or the nor 'e or train mines to a stop and the ohstruelion run he avoided.
